BAKING APPARATUS.

Specification of Letters Patent. Application filed December 15, 1909.

Patented July 4., 1911. Serial No. 533,171.

T 0 all whom it may concern:

Be it known that I, FREEMAN A. CALLEY, a citizen of the United States,and resident of Franklin, in the county of Merrimack and State of NewHampshire, have invented an Improvement in Baking Apparatus, of whichthe following description, in con nection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

My present invention is an improvement on my patented apparatus, N 0.909,988, patented January 19, 1909, whereby its capacity is enlargedwithout increasing the external size of the holding vessel, and it isrendered more easy to clean, and generally more eflicient than mypreceding apparatus.

The present apparatus is intended not only for baking beans, but meat,poultry, brown bread, and is otherwise adapted for general use.

The constructional details and further advantages of my invention willbe pointed out more fully in the following description and the inventionfurther defined in the claims.

In the drawings, Figure l is a central vertical sectional View of thepreferred embodiment of my invention; Fig. 2 is a similar sectional viewof a modified construction; and Fig. 3 is a horizontal sectional viewtaken on the line 33, Fig. 2.

The apparatus consists, as before, of an outside can or receptacle 1 andan inner can or receptacle 2, separated by any suitable means, as by aseparator 3 placed between their bottoms. The outside receptacle hasopposite handles 4, and the inner receptacle, as herein shown, extendsat its to edge 5 approximately even with the top edge of the outerreceptacle, thereby gaining space for a greatly increased amount of foodto be baked. This is made possible by the construction of the top, whichmy present invention primarily relates to. As shown in Fig. 1, I providea water tank 6 whose outer sides extend upwardly at 7 and continuedownwardly to constitute a flange 8 which fits tightly down over theupper portion of the receptacle 1. The bottom 9 of this water tankextends straight across the apparatus. The tank is provided at itsmiddle with a large central hole 10 opening at 11 approximately flushwith the top edge of the tank. A cover 12 has a peripheral flange 13which fits tightly over the top edge 7 of the tank and is provided wltha tubes 15, 16, said handle 14 whereby it may be removed from said tank.A vent, herein shown as a small tube 15, soldered or otherwise securedon the bottom 9 of the tank, extends out through the side wall of thetank and is provided at its outer end with a vertical glass sight tube16.

In using the apparatus, the top is removed from the receptacles, and theinner receptacle 2 is filled with the desired quantity of material whichis to be baked. There upon the tank portion of the top is put in place,as shown in Fig. 1, the tank is filled to the desired height ,withwater, and the cover 12 is then put in place. As the baking heat raisesthe temperature of the water, the steam therefrom rises and passes downthrough the opening 10 in large volume, surrounding the receptacle 2 andpermeating its contents. As the entire apparatus is practically sealed,this steam soon attains a superheated condition, all as fully explainedin my before-mentioned patent. The user can ascertain at a glance bylooking at the tube 16 at any time the height of the water remaining inthe tank 6, and as soon as the water has become nearly exhaustedtherefrom, that fact will be indicated by the escape of steam throughthe tube 15 being then uncovered by the lowering of the water in thetank 6.

In Figs. 2 and 3 I have carried out the same object by making a centraltank 17 whose bottom 18 extends beyond the outer walls 19 of the tank toa vertical inclosing flange 20 of the top whose lower portion 21 fitsdown onto the receptacle 1 in the same manner as the flange 8 of thepreviously described top, the whole being closed by a cover 22substantially the same as before. The tubes 15 and 16 are the same, theformer being soldered onto the bottom of the tank the same as before. Topermit the communication of the steam from the tank 18 to the contentsbelow, I provide a series of holes 23 through the outer portion of thebottom next to the vertical flange 20. The operation is substantiallythe same as before, excepting that the steam is not driven in such largevolume directly onto the contents of the inner receptacle 2 as in thepreferred construction. I also prefer the con struction shown in Fig. 1as it is easy to clean. In both instances, however, the apparatus ismuch easier to clean than my previous constructions inasmuch as theremoval of the cover leaves all the'interior parts in position to bevery readily inspected and cleaned.

Besides the provision for easily cleaning the inside of the top, I wishto make clear the important advantage before mentioned that thisprovision for a large flow of steam and the construction in generalaffords quicker baking of the beans, meat, or the like, and the user isable to tell when the meat is nearly done by inspecting the tube, Asexplained in my previous patent, the amount of water is regulatedto thenecessities of the case, so that when the water is almost out the usermay know that the baking is practically finished, and when the water isout, the blowing out of the steam through the tube 15 also indicatesthat fact. By having the handles at the side, the contents of theapparatus may be turned out very readily simply by tipping the entireapparatus edgewise, the top having first been removed.

Having described my invention, what I 7 claim as new, and desire tosecure by Letters Patent is V v 1. An apparatus of the kind described,comprising two cans, one within the other, having an annular steam-spacebetween them, a top member fitting tightly onto the outer can andinclosing the inner can and intervening steam-space, and provided with atransverse bottom and two upwardly extending concentric annular wallsforming two chambers, one for water and the other for steam from saidwater, the latter chamj her having free communication through saidbottom with said annular steam space, a

cover for said top member, and a signal tube extending along said bottomfrom the water chamber out through the side of the top member andterminating in an upright glass portion.

2. In an apparatus of the kind described,

a lower receptacle, a top fitting thereon having a bottom extendingentirely across the same, and two outer walls extending upwardlytherefrom approximately parallel to each other, the outermost of saidwalls being slightly higher than the other wall, a cover removably andtightly fitting the outermost of said walls, said bottom having a seriesof holes 23 through the portion of said bottom which is between saidwalls, and the inner of said two walls forming with said bottom a tank,open at its upper side, to hold water and deliver steam therefrom to thespace between the said walls and thence through said holes to the lowerreceptacle.

3. In combination, a lower outer receptacle, an inner receptacledisposed therein to leave an annular space between said receptacles, atop fitting the outer of said receptacles with a removable closurefitted thereto, said top carrying a water tank and having walls spacedapart adjacent its periphery, the annular space thus formed beingdirectly above the aforesaid annular space, and communications beingprovided from said tank to the latter annular space and also betweensaid annular spaces at intervals therearound.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
